Special BabySmartTM compatible child seats,
designed for use with the Mercedes-Benz
system, are required for use with the
BabySmartTM air bag deactivation system.
Please contact an authorized Mercedes-Benz
Center for information on availability. With
the special child seat installed properly, the
front passenger front air bag will not deploy.
The 4/ indicator lamp : will be
illuminated, except with the SmartKey
removed from the starter switch or with the
starter switch in position 0.
The system does not deactivate the window
curtain air bag and the Emergency Tensioning
Device (ETD).
Self-test BabySmart™ without special
child seat installed
After turning the SmartKey in the starter
switch to position 1 or 2 the 4/
indicator lamp comes on for approximately
6 seconds and then goes out.
If the 4/ indicator lamp should not
come on or is continuously lit, the system is
not functioning. You must see an authorized
Mercedes-Benz Center before seating any
child on the front passenger seat. More
information can be found in the “Practical
hints” section (Y page 220).
GWarning!
Do not place powered-on laptops, mobile
phones, electronic tags such as those used in
ski passes and like electronic devices on the
front passenger seat. Signals from such
devices may interfere with the BabySmartTM
air bag deactivation system. Such signal
interference may cause the 4/
indicator lamp not to come on during self-test
or be continuously lit, indicating that the
system is not functioning.
GWarning!
The BabySmartTM air bag deactivation system
will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmartTM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness off the BabySmartTM air bag
deactivation system. The bottom of the child
seat must make full contact with the front
passenger seat cushion. An incorrectly
mounted child seat could cause injuries to the
child in case of an accident, instead of
protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
Seat belts
Safety notes
The use of seat belts and infant and child
restraint systems is required by law in all 50
states, the District of Columbia, the U.S.
territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened whenever the vehicle is in motion.
For information on infants and children
traveling with you in the vehicle and restraint
systems for infants and children, see
“Children in the vehicle” (Y page 44).
GWarning!
Always fasten your seat belt before driving off.
Always make sure all of your passengers are

of the child, and secure child restraint with
the vehicle’s seat belt according to the child
seat manufacturer’s instructions.
GWarning!
Infants and small children should never share
a seat belt with another occupant. During an
accident, they could be crushed between the
occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Position
shoulder belt across chest and shoulder, not
face or neck. A booster seat may be
necessary to achieve proper seat belt
positioning for children over 41 lb (18 kg) until
they reach a height where a lap/shoulder belt
fits properly without a booster.
When the child restraint is not in use, remove
it from the vehicle or secure it with the seat
belt to prevent the child restraint from
becoming a projectile in the event of an
accident.
Installation of infant and child restraint
systems
GObserve Safety notes, see page 44.GWarning!
Always lock the seat backrests in their upright
position when the rear seats are occupied by
passengers, before installing top tether
straps, or the extended cargo compartment is
not in use. Make sure that seat backrests are
secured properly by pushing and pulling on
the seat backrests. If a seat backrest is not
locked properly, the seat backrest could fold.
The child seat would no longer be supported
properly or positioned to provide its intended
benefit. That could cause serious or even fatal
injuries.
This vehicle is equipped with tether
anchorages for a top tether strap at each of
the rear seating positions. The anchorage
rings are located on the floor behind each rear
seat.
Top tether straps enable an additional
connection to be made between child
restraint systems secured with LATCH-type
anchors and rear seats. This can further
reduce the risk of injury.
XRemove the cargo compartment cover
blind, if installed (Y page 129).
XGuide the top tether strap between head
restraint and top of the seat backrest.
The head restraint must be installed and
positioned such that the top tether strap
can pass freely between the head restraint
and top of the seat backrest.
XMake sure the top tether strap is not
twisted.
XFold up anchorage ring :.XSecurely fasten hook ;, which is part of
top tether strap, to anchorage ring :.
